Cable modem and slow VPN connection

User has been using Road runner cable modem and Cisco Client VPN, happily for 1 1/2 years. 2 months ago the speed suddenly slowed down, to the point she would rather dial in using a phone line connection. Cable Modem and Linksys router have been replaced.
User went to friends's house who uses SBC DSL and VPN worked great.
windows xp SP1
Linksys BEFSR41 (also tested connecting directly into the cable modem and bypassing Linksys)
Mcafee 4.5.1 sp1 - up to date
Road runner vendor claims nothing changed on their end and speed is good.
IE6 sp1 - works great when NOT connected to the VPN.
added dns/wins servers.
I have uninstalled/reinstalled VPN software.

Any help would be great!

The Cisco VPN client has a SetMTU utility that installed with it. Use this Utility and try setting the MTU to 1300.
Try updating the VPN client? What version have you re-installed?
You're sure she didn't install XP SP2?

Find another neighbor that has the same cable connection and try from there?

Very odd, indeed, that everything else is fast without the VPn client running.
Nothing changed on the VPN server end at the company? Are you the company support person? What is on the VPN connection end? VPN3000 series concentrator? PIX FW?
Just a thought...if the user has other machines accessing the internet through the same connection...this could very likely be an issue with file sharing or a Virus that is bogging down the connection...VPNs are bandwidth hogs so speed issues are very noticable...the end user may not notice a difference when web browsing...but that does not mean the issue is not there.

Solution ended up being - replaced the cable modem for a 2nd time. Connection is running fast now.
